  • Publication number: 20240065670
    Abstract: An image-free ultrasound system comprises ultrasound transducers, an ultrasound module, flow restrictors, a pulse detection module, and a measurement module. The ultrasound transducers are positioned at arteries to generate first signals based on blood flow and pulse propagation in the arteries. The ultrasound module is in communication with each ultrasound transducer to generate characteristic waves based on the generated first signals at the ultrasound transducers. The flow restrictors at the arteries restrict blood flow and to generate second signals based on the blood flow in the arteries. The pulse detection module is in communication with each flow restrictor to generate pulse waves. The measurement module is in communication with the ultrasound module and the pulse detection module to receive the generated characteristic waves and the pulse waves respectively, where the early vascular health markers are measured by the measurement module based on the characteristic waves and the pulse waves.

  • Publication number: 20230329667
    Abstract: A system for measurement of non-invasive and calibration-free blood pressure (BP) is disclosed. The system comprises a measurement probe (302) which is in contact with a person’s skin. The measurement probe (302) comprises a first array of sensors (302-1) and a second array of sensors (302-2). The first array of sensors (302-1) determines a force exerted on skin (304) and the second array of sensors (302-2) determines a compression-decompression characteristics of the arteries through skin. The force exerted on skin and the compression-decompression characteristics of the arteries are used to determine indices indicative of the material properties of the vessel. Based on the indices indicative of the material properties of the vessel, blood pressure and continuous transmural pressure waveform may be determined.

  • Patent number: 11737723
    Abstract: The embodiments herein provide a system for calibration-free cuff-less evaluation of blood pressure. The system includes an ultrasound-based arterial compliance probes and a controller unit connected to the said probe. The ultrasound transducers are configured to measure the change in arterial dimensions, pulse wave velocity, and other character traits of an arterial segment over continuous cardiac cycle, which is then used to evaluate blood pressure parameters without any calibration procedure using dedicated mathematical models.

  • Publication number: 20230210497
    Abstract: Embodiments of the present disclosure are directed to a vessel-wall-monitoring device (100) and a method for identifying the walls of blood vessel in a body. The method includes receiving, by the vessel-wall-monitoring device (100), a plurality of ultrasound echo signals from a transducer, wherein the plurality of ultrasound echo signals are transmitted to the transducer from locations of the blood vessel, extracting at least two consecutive ultrasound frames from the plurality of ultrasound echo signals, determining a shift between the at least two consecutive ultrasound frames by comparing samples of the at least two consecutive ultrasound frames, and identifying, a proximal wall and a distal wall of the blood vessel based on the shift between the at least two consecutive ultrasound frames.

  • Publication number: 20220054199
    Abstract: The invention in its various embodiments relates to a method of providing surgical guidance and targeting in robotic surgery systems. The method utilizes data from a navigation system in tandem with 2-dimensional (2D) intra-operative imaging data. 2D intra-operative image data is superimposed with a pre-operative 3-dimensional (3D) image and surgery plans made in the pre-operative image coordinate system. The superimposition augments real-time intraoperative navigation for achieving image guided surgery in robotic surgery systems. Also, a robotic surgery system that incorporates the method of providing surgical guidance and targeting is disclosed. The advantages include minimizing radiation exposure to a patient by avoiding intra-operative volumetric imaging, mobility of tools, imager and robot in and out of the operating space without the need for re-calibration, and relaxing the need for repeating precise imaging positions.
